A Judgment Method for Slipping and Broken Steel Bar on High-speed Wire Rod

Abstract

The invention provides a judging method for rebar slipping breaking on a high-speed wire. In a steel rolling control system of a steel rolling wire workshop, through a high-speed computation PLC, tracking is conducted according to a signal of a hot metal detector of steel rolling before a steel rolling reducing sizing mill works. After two seconds of delaying, whether the torque of reducing sizing is larger than 10% is judged, if yes, the condition that a rolling mill conducts occluding steel normally is showed; and if the torque of reducing sizing is lower than 10%, the condition that the rolling mill does not conduct occluding steel normally is showed, thus slipping steel heaping is judged, a steel heaping breaking procedure is started, an upstream flying shear is controlled to conduct breaking, failure treatment is conducted in advance, and rebars in the rolling mill are reduced. The judging method is high in judging accuracy rate, and failure treatment time is reduced by 50% or above.

Description

technical field [0001] The invention relates to the technical field of production control in steel rolling and wire rod workshops, in particular to a method for judging the slipping and breaking of steel bars on high-speed wire rods. Background technique [0002] There are more and more varieties in the steel rolling workshop, and the large-scale rolling is also getting bigger and bigger. At present, the maximum specification of the advanced high-speed wire workshop can be rolled to Φ26mm, but when rolling large specifications, there is a kind of common The problem is that on the reducing and sizing rolling mill rolled in the high-speed area, due to the low temperature of the head, it cannot be bitten into the rolling mill normally, resulting in piled steel, and the normal fishing line proximity switch detection cannot detect the fault normally. , At the same time, due to the large size of wire rod and steel bar, it is more difficult to handle, it consumes more time and manp...

Problems solved by technology

[0003] Aiming at the problem that steel bars cannot enter the high-speed rolling mill when rolling large-size wire rods, resulting in long production fault processing time, time-consuming and labor-intensive problems, the purpose of the present invention is to provide a high-speed wire rod with high judgment accuracy and reduce fault processing time.
